RELEASE NOTES:
v0.1 -> Last stable commit on develop branch before enhancement-10-harmony
v0.2 -> Merge of enhancement-10-harmony to include NGFI RRH + New Interface for RF/BBU
v0.3 -> Last stable commit on develop branch before the merge of feature-131-new-license. This is the last commit with GPL License
v0.4 -> Merge of feature-131-new-license. It closes issue#131 and changes the license to OAI Public License V1.0
v0.5 -> Merge of enhancement-10-harmony-lts. It includes fixes for Ubuntu 16.04 support
v0.5.1 -> Merge of bugfix-137-uplink-fixes. It includes stablity fixes for eNB
v0.5.2 -> Last version with old code for oaisim (abstraction mode works)
v0.6 -> RRH functionality, UE greatly improved, better TDD support,
a lot of bugs fixed. WARNING: oaisim in PHY abstraction mode does not
work, you need to use v0.5.2 for that.
v0.6.1 -> Mostly bugfixes. This is the last version without NFAPI.
v1.0.0 -> January 2019. This version first implements the architectural split described in doc/oai_lte_enb_func_split_arch.png picture.
Only FAPI, nFAPI and IF4.5 interfaces are implemented.
Repository tree structure prepares future integrations of features such as LTE-M, nbIOT or 5G-NR.
Preliminary X2 support has been implemented.
S1-flex has been introduced.
New tools: config library, telnet server, ...
A lot of bugfixes and a proper automated Continuous Integration process validates contributions.
v1.0.1 -> February 2019: Bug fix for the UE L1 simulator.
v1.0.2 -> February 2019: Full OAI support for 3.13.1 UHD
Forked from
oai / openairinterface5G

- size of PUCCH has been fixed to:
- 2 RBs for N_RB_UL = 25 (1 RB at top of resource grid, 1 RB at bottom)
- 4 RBs for N_RB_UL = 50
- 6 RBs for N_RB_UL = 100
this is arbitrary and will need some rework at some point.
This may be also wrong. PUCCH size actually depends on DL traffic
(if the ack/nack is not done in PUSCH) and scheduling request
configurations.
- add sched_frame %= 1024 at one needed place
- reserve RBs for retransmission
this was not done so new transmissions were scheduled in the same
RBs. Since the code works with the notion of 'first_rb' only, it
was decided to skip all RBs lower than those retransmitted. This
works but is not correct (imagine we have to retransmit RB 23, then
all RBs < 23 will not be used for new transmission). The work to
fix this properly is complex, a lot has to change, so let's do it
this simple way for now.
- sort_ue_ul was not correct
- add the function maxround_ul to use the correct 'round' (the one
from DL was used, which is totally wrong)
- be sure to use the correct frame/subframe to get the correct HARQ pid| Name | Last commit | Last update |
